5.0 out of 5 starsCompact Packaging Takes Little Space, Last At Least As Good As Amazonbasics AAA

Reviewed in the United States on November 13, 2018

I have lots of devices that use AAA cells and like buying them in bulk. This very inexpensive (as of this review) pack of 48 turned out to be better than I expected. After buying Duracell for years I tried Amazonbasics AAA and now these ACDelco cells. I am very pleased.

These are the least expensive AAA cells I've tried and they are lasting at least as long as the Amazon Basics AAA batteries I tried before. Besides the batteries themselves their packaging is perfect for me. The small rectangular plastic pack opens easily, takes little space in my drawer, and I can pull out individual batteries. Amazonbasics had 4 battery groups wrapped together and it was a pain to get just one battery by comparison.

As long as they last the same AAA batteries are pretty much the same across brands I think. That leaves price and convenience as differentiators. These win on both counts over others I've tried and that gets 5 stars from me.

These batteries were defective and dangerous. I put a set of four in a flashlight and within five minutes the flashlight got very hot and started to emit a burning smell. I opened the flashlight and dumped the batteries out on the floor. They were too hot to touch. I tried a second set of four in the flashlight and the same thing happened. The flashlight I used worked fine with another brand of AAA batteries. I called Amazon customer service immediately to alert them of this issue and suggested that these batteries be recalled and tested for safety.

End of July 2019 update.We seek a long lasting powerful battery. This small collection is simply average based on a high price per unit cost determination.I received my full 48 pack of AAA's and began using 4 of them inside new liquid soap dispenser with one minor failure: In order to get the dispenser to work, it took 12 batteries instead of the required 4. Our first reaction was that we received additional defective pumps. Wrong. The batteries were the source of defects; NOT the pumps. I use a simple testing method that meets most of our needs. When possible, I only use known fully charged batteries; not reused. One sample is insufficient to paint the batteries totally bad, but... I'll follow ACDelco's batteries for follow-up as we progress

Bought these six months ago mainly to use in roku remotes and small flashlights. The ones I had in a couple of flashlights exploded within three months. The ones in the Rokus don’t last a month. The previous brand lasted at least six months. Given how often I need to replace them, and two ruined flashlights, these are pretty expensive batteries.
